This can yield such text to be disclosed to web sites (when one clicks with the middle button in some form) and to other applications using the same X server (without needing any action from the user).This behavior exists in various applications like browsers, when focusing the address bar (I saw that in Pale Moon). Dunno if that is related to the GTK toolkit. The common behavior for applications is that text is only copied to primary if it is actively selected.
Here, with LibreOffice, this is worse, because this occurs whenever the LibreOffice window gets the focus. As a comparison, with Atril, when I choose "Save As...", the file name (without the extension) gets selected and the PRIMARY selection is modified (it gets this selection), which is bad. But at least, when I modify the PRIMARY selection by selecting something in another application and the focus is given back to the "Save As..." window, the PRIMARY selection is *not* modified (contrary to what happens with LibreOffice). -- Vincent Lefèvre <vincent () vinc17 net> - Web: <https://www.vinc17.net/> 100% accessible validated (X)HTML - Blog: <https://www.vinc17.net/blog/> Work: CR INRIA - computer arithmetic / Pascaline project (LIP, ENS-Lyon)
